Do you mean that the black screen on exiting emulator only appears on Grid and Filter Grid layouts?

It's just a workaround until we figure out what is the cause of ffmpeg decoder consuming too much CPU on certain configurations.

I know what is going on here. Two things:
Static effect is also a video. Try to encapsulete the static.mp4 in AVI container (or any other mp4 that sits inside the theme folder of your choice) as it seems to be the cause of 100% CPU usage.
When you test themes make sure you distinguish two types:
- Ones that redraw on each frame and maintain 60fps
- Ones that redraw only on transitions, they redraw only at the currently played video fps
The first group is what you should focus on as it's the most affected by the threaded optimization flag set to auto.

On what default theme you have 100% of CPU usage with threaded optimizations set to off?

Great news. Could you elaborate a bit more please about that static monitor effect? I'm not entirely sure what are you referring to. You were trying default themes right?
Regarding the threaded optimizations, it should be set to off anyway for nvidia cards as it slows down the transitions and introduce more stuttering. I wanted to set this off by default, but I need to figure out how to make the nvapi.dll calls to compile under MinGW as it seems that this api is not multiplatform.

I'm uploading a video showing how all that what I mentioned affects my CPU usage.

I did my test on 2.5.1. Please make sure your nv profile has correctly bound exe in the nvidia inspector

If you have nvidia card disable Threaded Optimization just for attract mode in nvidia control panel. This will reduce cpu usage by 25%. Another 25% can be reduced by forcing Buffer-flipping mode to ON in nVidia Profile Inspector also just for AM. This last option will disable double/triplebuffering though, so AM will be more prone to stuttering on artwork reloading
With those 2 flags on and with mp4 in avi containers I get around 5% of CPU usage, with spikes at around 11% on reloading ( can't tell exactly as my cpu is downclocking )
And one more thing, just in case. Make sure you disabled Focus Assist in Windows 10.

Would someone please experiencing the black screen on exit provide the following:
mame.ini
gpu brand and model
Windows 10 version and build number.
(Press Win+R and type winver and press enter)
When we are able to reproduce the problem maybe we could also find a solution for a black screen in fullscreen mode.

« on: December 09, 2018, 10:27:04 AM »
I think you all deserve an explanation of what is the purpose of this poll. My moderate OCD dictates me to make Attract Mode stutter free, able to sustain a constant 60fps even on Raspberry Pi. I have a proof of concept of asynchronous image loader with caching, so you will not longer need rawset_index_offset property. That means non blocking loading of resources that aren't yet on the screen, so in theory even if you write for example just an array of 100 add_image or add_artwork and cycle through games AM should keep 60fps. But first thing to fix is any other source of stuttering not loading related. The differences between Windows 10 and lower versions for example force different approaches of syncing, as the new DWM gets in the way. Vsync and double/triple buffering in SFML works differently on each window mode and differently in multimonitor mode, and even when you have your dpi scaling other than 100%. I have it almost fixed for Windows, but tests wil be required on all platforms to make sure I sync accordingly for each platform. I already got myself a mac and waiting for RPI to arrive. So my personal purpose of the poll is to let me know which platforms are commonly used so I prioritize this fairly.

« on: December 09, 2018, 02:07:59 AM »Didn't you guys just skew the results? Who is going to vote for Vista or Windows 8 now?
IMO - You should have limited the vote to one (primary) OS (like you started with). I, and many others, have AM on several OSes but I (and most likely others) always play games on one OS.
This poll is machine, not user oriented, so no, I don't believe the results are skewed in any way.

Not neccesarily. We have a database of 4529 forum users and I don't believe all of them have registered here to seek guidance in developing themes. Even though I'm not a fan of sending spam emails from administrators maybe in this case it would be beneficial to do so. That would give us a pretty good statistical sample.

It's not a problem. The only problem there is, is that we still can't find a solution for this excessive cpu consumption and we have to rely on workarounds.

I'm on Windows 10. You just extract ffmpeg.exe make 2 folders mp4 and avi. Then you copy or move your mp4 files to the mp4 folder. Make a bat file and paste the line from my post and add "pause" in the 2nd line. So now you should have 2 folders, ffmpeg.exe and a convert.bat in the directory. Doubleclick the bat and let the magic happen.
